Pro Tips

Upload Knowledge Files

Add PDFs, docs, or CSVs when building a GPT. This gives it specialized knowledge — your product docs, brand guide, or internal FAQ — without extra prompting.

Set a Strong System Prompt

The instruction field is your system prompt. Be explicit: role, tone, what to do, and critically, what NOT to do. This shapes every response.

Use GPT Actions for Live Data

Advanced: connect your GPT to an external API using Actions. This lets it fetch live data — CRM records, stock prices, or your internal database.

Check the Store Weekly

Top GPTs improve rapidly. The Featured section highlights newly excellent tools — a quick weekly browse can surface major workflow upgrades.

Watch Out For

  • Quality varies widely in the store — check the usage count and reviews before trusting a community-built GPT for important work.
  • Uploaded knowledge files can become outdated. Set a reminder to refresh them whenever your source documents change.
